Current Electronic Cigarette Use Among Adults Aged 18 and Over: United States, 2021.

Use of electronic cigarettes (e-cigarettes) has increased among some adults (1-3).Reducing the use of any tobacco product, including e-cigarettes, is a Healthy People 2030 objective (4). E-cigarettes have the potential to benefit some adults who smoke and are not pregnant if they are used as a complete substitute for regular cigarettes or other tobacco products (5). However, concerns exist about dual use of e-cigarettes and cigarettes (6-9). Use of e-cigarettes among young adults is also a concern because nicotine adversely impacts brain development, which continues into the early to mid-20s (5,10). This report uses 2021 National Health Interview Survey data to describe the percentage of adults aged 18 and over who currently use e-cigarettes by selected sociodemographic characteristics and dual use of e-cigarettes and cigarettes.
